They probably meant "do not trespass" or "no trespassing". Trespassing has a legal meaning. It means to enter a private property without permission. But that's not the only reason why you should enter.

In this case, the bridge could collapse at any time. That's why this area is closed to the public. I'd say here:

DO NOT ENTER - THIS BRIDGE IS AT RISK OF COLLAPSE!

4. Attack's risck

This is a sign on the Brazilian side of Iguazu fallsPortuguese: CUIDADO - NÃO ALIMENTE OS QUATIS - Risco de ataques English: CAUTION - DO NOT FEED THE QUATIS - Attack's risckA quati or coati is a raccoon-like animal found in Central and South America. Here are two:

At first, they look innocent and cute. But if you start to feed them, they get aggressive and can bite you. Now "Attack's risck" is not clear. You could either say, "attack risk". But you can translate literally here and say:

"RISK OF ATTACK"

5. DON'T OVERTAKE THE BANISTER

Again, we are in the Brazilian national park of Iguazu falls.This time, they're telling us:Portuguese: NÃO ULTRAPASSE O GUARDA-CORPUEnglish: DON'T OVERTAKE THE BANISTERSTotal nonsense! Am I on a racetrack or highway? It sounds like I can't go over, but can I go under the banister? The sign seems to tell us we can't. They probably meant: "Do not cross the guard rail".

5. And the winner is...

Now across the border on the Argentine side of the Iguazu falls, we see...:

Spanish: AREA DE USO EXCLUSIVO DE LOS FOTOGRAFOS HABILITADOS

English: AREA ABILITY JUST FOR PHOTOGRAPHERS AUTHORIZE

Well looks like we have a winner! This is complete gobbledegook! This should say:

"RESTRICTED AREA - AUTHORIZED PHOTOGRAPHERS ONLY."
